THE AURORA - A JOURNEY INTO THE NORTHERN LIGHTS project is a collection of trance music made
primarily by techno producers and remix-DJs based in Scandinavia. The concept presents the creative
energy of the north, that is the sound of Nordic Techno.
AURORA appears when highly charged particals from sunspots and solar flares
excite the thin gases of the upper atmosphere and make them glow. Displays are
most frequent in the spring and autumn because the Earth is then most nearly
in line with zones of the sun where sunspots are large and frequent. However,
Aurora may be most frequent during winter in certain areas.
The particles from the sun are deflected by the Earth’s magnetic poles (these poles
mark the axis of the Earth’s magnetic field and are not the same as the magnetic poles
which lines of magnetic forces are vertical). The particals then collide with oxygen and
nitrogen atoms, blocking away electrons to leave ions in excited states. These ions emit
radiation at various wave-lengths, creating the colours of the Aurora.
